| 英文摘要 | This study describes a facile and effective polymer-assisted route to synthesis of structurally uniform and electrochemically active manganese dioxide/multiwalled carbon nanotube (mno2/mwnt) nanocomposite and investigates the electrocatalytic activity of the synthetic mno2/mwnt nanocomposite toward the reduction of oxygen in alkaline media. poly(sodium 4-styrene sulfonate) (pss) used here as the polymer to assist the synthesis of the nanocomposite serves as a bifunctional molecule both for solubilizing mwnts into an aqueous solution and for tethering mn2+ precursor onto mwnt surfaces to facilitate the follow-up chemical deposition of mno2 to eventually on-spot grow mno2 nanoparticles onto mwnts. the synthetic mno2/mwnt nanocomposite has a uniform surface distribution and large coverage of mno2 nanoparticles onto mwnts, which was characterized with scanning electron microscopy (sem), x-ray diffraction (xrd), x-ray photoelectron spectroscopy (xps), and cyclic voltarnmetry (cv). the synthetic mno2/mwnt nanocomposite was studied with respect to its electrocatalytic activity toward the reduction of oxygen in alkaline media and was found to possess a good electrocatalytic activity toward the four-electron reduction of oxygen. the mno2/ mwnt nanocomposite synthesized with the polymer-assisted method could be potentially used as air electrode materials for catalytic reduction of o-2 in alkaline fuel cells and metal/air batteries. |
